(The growth of ice crystals from the vapor phase.)

Abstract

The growth forms of ice crystals <100 mu m in size vary remarkably with the water vapour diffusivity, and those of ice crystals >100 mu m vary slightly with the water vapour diffusivity. Moreover, the growth forms of ice crystals <100 mu m vary slightly with the thermal conductivity of the gas. Therefore, the growth forms of ice crystals depend not only on the T and the supersaturation, but also on the diffusion of water vapour, latent heat released by crystallization, and the crystal size. -I.S.
